Arches National Canyon, Utah Formed when wind and water weather (erode) softer material first.
Ventifact on Mt. Falconer - Canada Wind carries fine particles that work like a sand blaster (i.e. sand, silt, clay, and ice particles)
Desert pavement Formed in arid environments when wind carries finer, more lightweight particles such as sand away. Large particles are left behind and protect from further erosion
Loess Deposits - Banks, Pennsylvania Yellowish, fine grained silt and clay sized particles formed by glaciers millions of years ago; carried and deposited by wind.
Sand Dunes leeward windward leeward Piles of sand deposited by wind - Leeward side has a steeper slope leeward windward leeward
